Composer Tomoyuki Hayashi, who has worked as musical director for the international synthesizer player Kitaro, as well as for various other productions, left this CD for Kanebo's Sound Esthetic series in 1993. This blue version was produced after the green version, as was the case with the three other works by Shiho Yabuki. The original sound source of 10 tracks was expanded based on the image of "blue" such as relief, tranquility, comfort, sea, sky, as well as experiments with effects. It's not a conventional work, has various themes and a quality that gives the impression of having been well-crafted. One of great 90's CD production.
